Our online glossary is here to help you make sense of the terminology used in the cell phone industry. It covers mobile technologies, such as 3G and 4G, and even includes a bit of information on smartphone operating systems and the companies that make the cell phones and other mobile technology devices we all use.
There are a number of names and abbreviations that are used to refer to the pixel dimensions of displays on smartphones and tablets. Early displays were based on the old PC standard of the Video Graphics Array (VGA) resolution. They are VGA 640 x 480, QVGA 320 x 240, HVGA 480 x 320, WVGA 800 x 480, and FWVGA 854 x 480. Q stands for quarter, H for half, W for wide, FW for full wide. XGA resolution displays (1024 x 768) are not common on mobile devices, but many tablet displays make use of WXGA (wide XGA), which is commonly 1280 x 720 or 1280 x 800. Newer high end displays are often based on the 720p (1280 x 720) and 1080p (1920 x 1080) resolutions of HD televisions. Some derivative resolutions are qHD at 960 x 540, and nHD at 640 x 360.
Also known as: "FWVGA", "HVGA", "nHD", "qHD", "WVGA", "WXGA", "XGA"
